TABULATING MECHANISM FOR PRINTING TELEGRAPHS.

Application filed June 25, 1923. Serial No. 647,510.

T 017 whom it may concern:

Be it known that CARL Euro Names, a citizen of the'llnited States,residing at Brooklyn, in the county of Kings and State 6 of New York,has invented certain new and useful Improvements in TabulatingMechanisms for Printing Telegraphs, of' which the following is aspecification.

This invention relates to a tabulating and paragraphing mechanism. forprinting telegraphs.

Heretofore data in tabular form, when sent over printing telegraphcircuits, has necessitated the sending of a plurality of spacing signalsto the receiving printer between the various columns in order to prop:erly align the matter. A great portion of the line time is taken up insending these spacing signals and. such transmission, is slow andnecessarily costly.

The objects of the present invention are to provide a tabulating devicefor printing telegraphs which will eliminate the necessity of sendingspacing signals to step the spacing mechanism of a printing telegraphmachine for paragraphing and tabulating purposes, and such other objectsas are at tained by the preferred embodiment herein disclosed of whichFigure 1 is a fragmental and partially diagrammatic view showing thetabulating mechanism and circuits-and only so much of a printingtelegraph machine as will be necessary to understand the invention.

The details of the printing telegraph machine of which the fragmentalportions are here shown, are disclosed in copending application Ser. No.390,598, filed June 21,

1920, to which reference may be had for a complete description. Theparts of the printing machine are given the same reference numbers inthe present case as they have been in the co ending'application tofacilitate understan ing of the invention and its ap lication.

On the rawing 10 represents the printermagnet, 18 is the one of the fiveselector magnets which is energized when a spacing signal isreceived,'43 is the printer bail operating shaft, 116 is the carriageball race, 117 is one of the balls upon which the carriage islongitudinally and tiltably notch 3 and shoulder 4 formed thereon. A

control plate 5 is supported pivotally by members 6 and from rod 1.Pivotally secured to an extension of member 6 is a hook member 8 whichis guided by and slidably mounted on an extension 9 'of shift lock arm133. A spring 11 secured at one end to a collar 1.2 on rod- 1 and at theother end to member 7 is normally stressed in a manner'to force plate 5rearwardly'and to the left in the figure, against shoulder 4 as shown.Extending downward from memher 6 is a contact carrying member 13 uponwhich are mounted contact springs 14 and 15 separated by insulation 16.An arm 1.7 secured to printer bail shaft 43 is arranged to co-act withcontacts 14 and 15. A pair of contact springs 19 and 20 are normallyheld in open relation and controlled by a member 21 which is pivotallycarried by a pivoted arm 22. Arm 22 is normally held against a stop 23by a spring 24.. Member 22 is held'against a stop 25 by a spring 26 andhas a cam surface adapted to ride up on a pin 28. It will be understoodthat members 22, 23, 24, 25 and 28 are suitably supported from theprinter frame not shown. An arm 29 secured to printer bail shaft 43 isadapted to engage a shoulder on member 21 as shown. Pivotally mounted ona suitable support (not shown) is an arm 30 which carries a member .31.adapted to engage a projection on hook member 8 only when the printercarriage is in shifted position. An extension 32 of a printer letteractuating bar is pivotally connected to arm 30. A series of slots. 33cut into plate .5 are adapted to receive, stopmembers 34. A member 35carried by ball guide rack 118 is adapted to engage stops 34.

In addition to the circuits shown in application Ser. No. 390,598through magnets 10 and 18, circuits as here shown from battery 36through contacts 14, 15,19 and 20,

magnet 10 and the N0. 3 magnet 18.

resistance 37 to magnet 18, and through magnet '10 are provided.

Upcwrfvirm.

To operate the 'tabulating mechanism stops 1-1- are first properlvarranged in slots #13 in accordance with the columner spacing desired.The matter to be printed is trans mitted in the usual way. To spacebetween columns a shift signal is sent to lock the carriage in shiftedposition as described in application Ser. No. 390,595. \Vith thecarriage in shifted position hook member 8 is moved by member 1) in aposition to be engaged by member 3 A signal is then transmitted toactuate extension 32. Magnet 10 will be energired on this signal by thecircuits shown in Ser. No. 390,598 and will move extension 32 to theleft in Figure 1, causing member 31 to engage member 8 and move itdownward. Movement of S downward Will rock plate 5 forward againstthe/tension of spring 11 and as plate 5 is moved off shoulder 4, spring11 will force it into notch 3 where it will be locked. Movement of plate5 into notch 3 throws contacts 11 and 15 against arm 17 after magnet 10has de-energizcd' and closes these contacts. This closes a circuitthrough Energization of this magnet 18 sets the printer mechanism sothat the spacing actuating bar will be operated as 10 energizes in thiscircuit. As 10 energizes, in addition to operating the spacingmechanism, arm 17 will be actuated to permit springs 1st and 15 toseparate, and at the same time arm 29 will move member 21 in a manner topermit contacts 19 and 20 to close before contacts 14 and 15 open. Theenergizing circuit for magnet 10 will be shifted through contacts 19-and 20 as the movement of shaft 43 progresses. As the end of theenergizing stroke of 10 is reached surface 27 of member 21 will ride upon pin 28 and member 21 will be disengaged from arm 29. Disengagement ofmember 21 permits spring 2.4. to become effective and a um 22 togetherwith member 21 will move forward and will separate contacts 19 and 20,interrupting the energizing circuit for 10. Magnet 1.0

- and the printer bail parts will restore under influence of a spring(not shown) and '17 will again close contacts 14 and 15. This cycle willbe repeated resulting in spacing of the carriage until member 35 engagesa stop 34which has been locked in forward position by movement of plate5 into notch 8. When this occurs the movement of ball guide rack 118will carry plate 5 with it to the right until plate 5 is in a positionto slide over shoulder at under the tension of spring 11. Movement ofplate 5 over s oulder 1 moves contacts 14: and 15 into position wherethey can not be closed by arm 17 and upon the restoration of magnet 10the printer will come to rest.

It will be obvious that this mechanism may be made to operateindependently of the carriage shift by simply providing a specialactuating bar which will cause operation of 8' each time its signal isreceived. It will also be clear that the invention is applicable toother commonly known telegraph printers such forcxample as typewheel anddisc selector machines and is not limited to the particular embodimentherein. disclosed.

Having described one form of my'invention what is desired to be securedby Letters Patentand claimed as new is:
